• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach 2 ((lang xa) OR (lang van)) hoi. ((hieu va) OR (lieu va)) cam xuc va hanh dai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach 2 ((lang xa) OR (lang van)) hoi. ((hieu va) or (lieu va)) cam xuc va hanh dai cua triet".
